The good or ill of a man lies within his own will.
Act well your given part; the choice rests not with you.
No man is free who is not master of himself... Is freedom anything else than the power of living as we choose?
Freedom isn't the right or ability to do whatever you please. Freedom comes from understanding the limits of our own power and the inherent limits set in place by nature. By accepting life's limits and inevitabilities and working with them rather than fighting them, you become truly free.
Contentment, as it is a short road and pleasant, has great delight and little trouble.
What disturbs and alarms man are not the things, but his opinions and fancies about the things.
